My first post:
Two unrelated problems. I have a 7 year old Alpha 35C boiler as part of a Flow Smart installation with a 50 litre Thermal Store on the primary circuit thats heats up the inflowing cold main before it entering the boiler via a mixer valve. The Thermal Store tank is sited in the same cupboard as the boiler directly below resting on the floor. The tank has a drain valve at the bottom which has started to leak. It's unlike any valve I've seen before as it's just a lightly knurled brass threaded nut (no flats) with a plastic tapered pipe that's like a hose end (ridged). I tried slightly loosening and tightening the brass nut but to avail. It's still dripping. As a temporary fix I've connected a short piece of hosepipe to the black hose end secured with a jubilee clip, the hosepipe is attached to short piece of copper pipe with a stopend. A bit Heath Robertson but so far so good.
Any seen this before and any suggestions as to how to fix this properly ?
Second problem is more long standing. Most mornings over the last 5-6 months when the heating comes on the first thing, the boiler makes a whining noise - my wife likened it to whale-song (!). I'm thinking its bearings either in the fan or the pump but can't isolate which. Again previous experience of similar issues and suggestions as to how to diagnose would be much appreciated.
